MRAC Series Miniature Rectangular, Removable Contacts
Removable contacts offer a substantial savings
of time, labor and a great flexibility in the choice
of circuitry. The contact is easily removed with
the hand tool depicted and then placed by
hand or with a simple insertion tool.
The MRAC Series is an important extension of the MRA line featuring a variety
of crimp and solder removable contact styles. Except for body thickness, they
are similar and interchangeable with the MRA Series.

JACKSCREWS & JACKSOCKETS
Polarized jackscrews give the ease and
assurance of threaded positive coupling.
The actuating side consists of two turnable
screws, one male and one female, each with
knurled and slotted knobs. On the mating half
are the two fixed screws required to
complete the locking action. When mated,
the jackscrews may be locked with a safety
wire through the hole in the self-locking pin
(in the jackscrew shaft).

Note 1:When panel mounting the lock-tab half of a MRAC 34, MRAC 42 or MRAC 50 connector, flat washers
(.033 minimum thickness) should be used on the mounting screws to shim the molding away from the panel.
Note 2: Each code number indicates two units, i.e., the “MRE-VL” consists of two levers and two pivots
(unassembled*), and the “MRE-V” consists of two tabs.
Note 3: These units are supplied unassembled to facilitate handling. The pivot is easily assembled to the
lever merely by inserting the hooked end through the lever opening. It will automatically snap into proper
position. Patent #2,760,174.
